Hello Fellow Motorists,

Thanks to some spirited driving & peel-offs on my MCS, my factory run flats feel very slippery at 10K miles. I am considering upgrading to 17" wheels and non run-flats. I have the following questions:

1. I plan to buy 17" black Konig feathers. What else do I need to buy to install the wheels? Terms like spacers etc bother me, do I need them?

2. From I read so far, I don't expect any TPMS issue with the Konig. Am I right?

3. What non run-flat would you recommend for the 17"?

4. Would i get a better discount if I buy & install my tires at a local shop instead of buying them online? Any advice?

Thanks in advance for your replies (for my rookie questions).

Cheers,
Fundude
